The instrument switches to "Remote LLO" state. The [Setup] key is disabled.
7. To enable the [Setup] key, use the command &GTR.
8. To return to manual operation, see Chapter 13.8.9, "How to return to manual oper-
ation", on page 428.
Tip: Switching from manual operation to remote control and vice versa does not
affect the other instrument settings.
13.8.5 Establishing a remote control connection over LAN using socket
communication
This section provides an example on how to establish a remote control connection over
Telnet client and a simple sockets-based program example that can be further devel-
oped.
See also Chapter A.1, "Telnet program examples", on page 774.
The telnet client transmits information unencrypted. Therefore, for sensitive information
we recommend that you use a client which supports secure protocols, like SSH.
In the following example, we assume basic knowledge of programming and operation
of the controller. You can find information on the interface commands in the corre-
sponding manuals.
Setting up a Telnet connection
To control the software, only a Telnet program is required. The Telnet program is part of
every operating system.
1. On the instrument:
a) Enable the LAN interface.
See Chapter 13.7.1, "How to enable access via LAN", on page 415.
b) Enable "SCPI over LAN".
See Chapter 13.7.2, "How to activate LAN services", on page 415.
2. Connect the remote PC and the instrument in the same network.
See also Chapter 13.7.3, "How to connect to LAN", on page 415.
3. On the remote PC, start the Telnet program.
Enter the socket address.
The socket address is a combination of the IP address or the hostname of the
R&S SMA100B and the number of the port configured for remote-control via Telnet.
Tip: The R&S SMA100B uses the port number 5025 for remote connection via Tel-
net.
